* ARM: remove SPEAR entry in makefilePatrick Delaunay2023-03-061-1/+0

* arm64: Reduce PT size estimation complexityMarc Zyngier2023-03-061-75/+34
| | | | | | | | | | | | | | | | | | | | count_required_pts()'s complexity is high if mappings are not using the largest possible block size (due to some other requirement such as tracking dirty pages, for example). Let's switch to a method that follows the pattern established with the add_map() helper, and make it almost instantaneous instead of taking a large amount of time if 2MB mappings are in use instead of 1GB.

* arm64: Reduce add_map() complexityMarc Zyngier2023-03-061-48/+46
| | | | | | | | | | | | | | | | | | | | | | In the add_map() function, for each level it populates, it iterates from the root of the PT tree, making it ineficient if a mapping needs to occur past level 1. Instead, replace it with a recursive (and much simpler) algorithm that keeps the complexity as low as possible. With this, mapping 512GB at level 2 goes from several seconds down to not measurable on an A55 machine. We keep the block mappings at level 1 for now though.

* arm: cpu: Add optional CMOs by VAMarc Zyngier2023-03-064-26/+155
| | | | | | | | | | | | | | | | | | | | | | | | Exposing set/way cache maintenance to a virtual machine is unsafe, not least because the instructions are not permission-checked but also because they are not broadcast between CPUs. Consequently, KVM traps and emulates such maintenance in the host kernel using by-VA operations and looping over the stage-2 page-tables. However, when running under protected KVM, these instructions are not able to be emulated and will instead result in an exception being delivered to the guest. Introduce CONFIG_CMO_BY_VA_ONLY so that virtual platforms can select this option and perform by-VA cache maintenance instead of using the set/way instructions.
